Operation On Different Mains Type; Typical Installation In A Panel Or Other Enclosures - Danfoss AHF 005 Operating Instructions Manual

4 Installation
NB!
Do not fix the nut without using a second wrench for the screw.
If this is not observed, it might be possible to tear out the terminal when fixing the nut.

NB!
For UL approval use copper conductor only.

4.1.8 Operation on different mains type

TN Directly grounded star point
TN Indirectly grounded star point
IT Isolated star point
The filter module has been designed completely symmetrically for three phase operation and without reference to the star point or protective earth.

4.1.9 Typical installation in a panel or other enclosures

To avoid high frequency noise coupling keep a minimum distance of 150 mm (5.91 inches) to:
a) mains/supply wires
b) motor wires of frequency converter
c) control- and signal wires (voltage range < 48 V)
To obtain low resistive HF-connections, grounding, screening and other metallic connections (e. g. mounting plates, mounted units) should have a surface
as large as possible to metallic ground. Use grounding and potential equalisation wires with a cross section as large as possible (min. 10mm²) or thick
grounding tapes.
Use copper or tinned copper screened wires only, as steel screened wires are not suitable for high frequency applications. Connect the screen with metal
clamps or metal glands to the equalisation bars or PE-connections.
Inductive switching units (relay, magnetic contactor etc.) must always be equipped with varistors, RC-circuits or suppressor diodes.
